The invention discloses a bridge crane limiting and locking device, and relates to the technical field of cranes, the bridge crane limiting and locking device comprises a shaft sleeve, a movable cavity and a gravity limiting structure, the gravity limiting structure is arranged in the movable cavity, the gravity limiting structure comprises a limiting plate, a lifting rod and an elastic assembly, and the lifting rod is connected with the bottom of the limiting plate; the lifting rod is elastically connected to the inner side of the movable cavity through an elastic assembly, an inverted circular truncated cone block is arranged at the bottom end of the lifting rod, a plurality of clamping blocks are distributed on the periphery of the outer side of the circular truncated cone block, the clamping blocks are V-shaped blocks, inclined grooves clamped with the clamping blocks in a sliding mode are formed in the lower end of the shaft sleeve, and the inclined grooves are matched with the clamping blocks. A lifting hook is arranged at the bottom of the circular truncated cone block. After a heavy object is arranged on the hook, the elastic assembly can be compressed, the inclined groove is clamped with the clamping block, the circular truncated cone block cannot rotate in the movable cavity, the purpose that the lifting hook can be positioned when materials are hung is achieved, and the hook is prevented from driving the materials to rotate during lifting.

    本发明公开了一种桥式起重机限位锁定装置,涉及起重机技术领域,包括轴套、活动腔与重力限位结构,所述重力限位结构设置在活动腔内部,且重力限位结构包括限位板、升降杆与弹力组件,所述升降杆连接限位板底部,所述升降杆通过弹力组件弹性连接在活动腔内侧,所述升降杆底端设置有倒置的圆台块,所述圆台块外侧圆周分布有若干个卡块,所述卡块为V型块状,所述轴套下端设置与卡块滑动卡合的斜槽,所述斜槽与卡块相配合,所述圆台块底部设置有吊钩。本发明中挂钩上有重物之后弹力组件会被压缩,斜槽与卡块卡合,使圆台块不能在活动腔内转动,实现了悬挂物料能够使吊钩定位的目的,起重时防止挂钩带动物料转动。
